Ingredients

Scale

Cake

  • 1 box vanilla cake mix
  • 1/2 cup all-purpose flour
  • 1/2 cup granulated sugar
  • 3 large eggs
  • 1/2 teaspoon salt
  • 1 cup milk
  • 2 Tablespoons vegetable oil
  • 1 cup sour cream
  • 1 teaspoon vanilla extract

Frosting Filling

  • 3/4 cup unsalted butter, softened
  • 7 ounces marshmallow creme
  • 1 cup powdered sugar
  • 1/4 teaspoon salt
  • 1/2 teaspoon vanilla extract
  • 2 tablespoons heavy cream

Decoration

  • White chocolate candy melts, melted
  • Pink food coloring

Instructions

  1. Preheat Oven: Preheat your oven to 350°F and line two 9×13-inch baking sheets with parchment paper to prevent sticking.
  2. Prepare Cake Batter: In a large mixing bowl, combine the vanilla cake mix, all-purpose flour, granulated sugar, salt, eggs, milk, vegetable oil, sour cream, and vanilla extract. Mix thoroughly until you achieve a smooth, uniform batter.
  3. Spread and Bake Cakes: Divide the batter evenly between the two prepared baking sheets and spread into thin, even layers. If using a half-sheet pan, pour all batter onto it. Bake for 15-20 minutes or until a toothpick inserted into the cake comes out clean. Remove from the oven and allow cakes to cool completely.
  4. Cut Heart Shapes: Using a heart-shaped cookie cutter, cut out mini heart cakes from the cooled cake layers on both baking sheets. Set these aside for assembling.
  5. Make Frosting: In a mixing bowl, beat the softened butter until creamy. Add the marshmallow creme, powdered sugar, salt, vanilla extract, and heavy cream. Beat the mixture until it becomes light and fluffy.
  6. Assemble Cake Sandwiches: Spread a generous layer of frosting on one heart-shaped cake and top it with another to create a sandwich. Repeat with all heart cakes.
  7. Melt and Color Chocolate: Melt the white chocolate candy melts according to package instructions. Reserve a few tablespoons of plain melted white chocolate in a piping bag or small bowl. Stir pink food coloring into the remaining melted white chocolate until you have a smooth, light pink color.
  8. Coat Heart Cakes: Dip each heart-shaped cake sandwich into the pink melted chocolate to coat completely. Place dipped cakes on a wire rack with a baking sheet underneath to catch drips and allow the chocolate to set.
  9. Decorate with Drizzle: Using the reserved plain white melted chocolate, pipe or drizzle decorative designs over the pink-coated heart cakes to finish them beautifully.

Notes

  • Ensure cakes are completely cool before cutting and assembling to prevent crumbling.
  • Use a sharp heart-shaped cutter for clean edges on the mini cakes.
  • For easier dipping, chill the frosted heart cakes before coating in melted chocolate.
  • Pink food coloring is essential for the signature heart cake look; gel food coloring works best for vibrant color.
  • Store the finished heart cakes in an airtight container at room temperature for up to 3 days or refrigerate for longer freshness.
